In those who shot, the low-frequency component of heart rate variability rose from 2,019.7 to 3,418.1 (p=0.01) and the ratio of low to high frequency from 2.9 to 6.4 (p=0.02), while in the controls the ratio went from 2.8 to 3.7 without reaching significance. Nothing else moved, however: the standard deviation of the intervals stayed at 82 milliseconds, the high-frequency component did not change, and neither did the mean intervals during a pressure manoeuvre. The same study therefore points two ways, and three things stop us going further in any case. First, the authors only compared before and after within each group, never setting the two groups against each other. Second, the participants were overweight, with a body mass index around 29 and a third of their mass as fat. Third, there is the direction: a rising ratio is usually read as a shift towards sympathetic activity, although that reading is debated, so the result does not support the idea of archery as something that calms the heart.claim:arco-hrv-sedentari:revision:2026-09-28:2Mon, 28 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/health/archery-heart-rate-variability-sedentaryclaim:arco-hrv-sedentari:new_claim:2026-09-08:contestatoTue, 08 Sep 2026 08:00:00 GMT
